Blower and manifold must be removed to access the KS. You'll need a new set of gaskets for the blower and manifold to put it all back together.

Mine now has the problem of the blower itself is making bad bearing noise. Went to a PSE blower website and found a replacement for $650.00. I called and talked to a rep and they said if i got 100,000 miles out of an eaton blower then I did good. he also asked how often I changed the fluid. I said Nissan didnt have a change interval for it. That lit him up. He said it should be changed every 30,000 miles.
So lets see:
KS replacement $750.00-$1000.00
New blower $650.00

This really sucks!
